Delevingne has a cute, furry sidekick, but God love her for the fact that it's not a tiny dog. When the model arrived on set to shoot a Topshop ad campaign, she met—and subsequently fell in love with—the prop. She named him Cecil Delevingne, brought him home, and shortly thereafter, young Cecil got an Instagram account. He is now the most famous noncartoon rabbit in the world.

It's not just that she has a lion's face on her index finger and ohmygod that's so weird and fabulous. Or that she had it done in Rihanna's hotel room one night. Or even that she recently had the word BACON needled onto the underside of her foot. It's that the whole collection of tattoos suggests a weird, spontaneous, childlike exuberance for…everything.

She crosses her eyes, sticks out her tongue, and posts the whole unflattering picture on Instagram—over and over. She wears trucker hats, Bulls jerseys, and dumpy pants. Her lack of vanity is as refreshing as it is unprecedented.

Delevingne opened and closed the fall 2014 Chanel runway show, actually walking the runway with Lagerfeld at the end. Her joie de vivre makes her the perfect muse, and that she's earned the affection of the most esteemed designer in the world shows just how pivotal she has become to fashion. They're the perfect platonic couple.

You know how models are relentlessly dour? Like all of life is just so serious and burdensome? Delevingne is the first one who looks like she's having fun. Just look at the grin on her face at Stella McCartney's fall show. Her joy is infectious. When was the last time anyone said that about a runway model?

It's one thing for a supermodel to appear in a music video. That's a device as old as George Michael. It's quite another when Delevingne stars alongside a few hundred emojis while lip syncing to LL Cool J and Jennifer Lopez. And for the record, she's an amazingly good lip syncher.

"I was teased about [my brows] when I was young," Delevingne told Allure. "I hated them. I tried to pluck them, but my mother persuaded me not to." And now: a big shout-out to Mama Delevingne for inspiring a generation of women to stop tweezing.

They're both British, they're both kind of grungy, and they're both ridiculously pretty. But what we love about these ads isn't any of the above. What we love is that they look like they're actually friends—because they are.
